Keys
Almost all modern cars require a transponder key or fob in order to work, which provides security and protection against theft. These keys are programmed by a locksmith or authorized dealer to work with your car's system and specific model. It is expensive to replace them if they become lost, so it's a good idea to have spares in your possession. You can also find replacement key fobs on various websites and in many brick-and mortar auto shops. How can you be sure that the key you purchased is genuine? Do you know whether the unit is programmed to work with another vehicle or if yours can be programmed again?
To program a new car key, you must first ensure that your vehicle is running. Insert the key you want to program into the ignition, but do not turn it. You have only a few seconds before the system resets all commands and leaves the programming mode. It is important that you move quickly and do not wait between each step. Turn off the engine to stop this. Switch the key from "on" to "off" to test the system. There should be a chime to indicate that the process was successful. The door locks will go through a cycle.
Certain vehicles of recent years use rolling keys to stop thieves from using stolen keys to open the vehicle. The feature is still vulnerable to a technique dubbed replay attack. It allows thieves to record and later reproduce the signal from the key fob of the vehicle to open the car. To stop this, manufacturers added security features known as the CAN bus protocols to stop hackers from gaining access to the vehicle.
Certain manufacturers employ a specific encryption on their keys, which cannot be decoded using a simple program. It is best to only attempt this method if you have experience is in electronic devices. Check the manual of your car or look up the manufacturer's website to find out how to program it. The steps to follow will differ depending on the type of vehicle.
Transponder chips
Car keys that feature transponder chips need special programming to function. Any hardware store can make you a new car key, however the real challenge lies in integrating it with your vehicle. The key needs to be programmed to match the exact identification code on your car, or else it won't be able to start.
Transponder chips, used to prevent car theft are a standard feature of modern cars. The chip is a microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car is able to detect the signal, and starts the engine only if the signal matches the one programmed in the vehicle. The vehicle is also programmed to shut down when it detects an incompatible frequency. This makes it much more difficult for car thieves with no experience to wire a vehicle and start it.
A circuit board with an induction coil connects the key to the chip. When the key is put in the ignition the magnetic field is created around the transponder. This creates a signal which is absorbed by the coil and sent to the key's identification number. The key's identification code is sent back to the car and the engine is started when the identification number is in line with.
There are many methods to program a transponder keys, but they all involve using a special tool. These tools can be purchased on the internet or at most auto locksmiths. These tools are not expensive, but they are essential for programming your car's chip.
You can also use an unreprogrammable key that was programmed for a different vehicle. In this scenario you'll need sure that the key isn't damaged or that the transponder has been altered in any way. You can read the chip with a scanner, or a computer with an USB connector.
The process of reprogramming the transponder key is simple, however it requires an expertly designed software and scan tool. If you're just beginning, it's best to seek the assistance of an auto locksmith. Also, avoid buying secondhand keys, as they're probably already programmed and won't work with your car.
